Wack Period

So I have PCOS, and with PCOS i am super irregular. I hadn’t gotten my period in months, so i tried these new vitamins called ALANI NU balance. They did their job and brought back my period exactly 2 months after taking them. I stopped taking them at about 3 weeks, because we were moving and I honestly have yet to find the bottle of vitamins.

Well fast forward a month exactly after i got my other period, i got it again and I was so happy because even without taking the vitamins anymore I got my period exactly a month afterwards. The only downside is that i have severe cramping and a VERY heavy flow. I am normally super light with just spotting most of the days. Well today is day 3 and it is to the point where every 2 hours i am rushing to change my tampon because if not I am staining my undies. I am also having a lot of clots.

Is this normal? I don’t know what to do and if i should continue the vitamins if i find them!!
